13. Siphon/neutralisation/condensate pump

Condensate drain without neutralisation
If low sulphur fuel oil EL (sulphur content < 50 mg/kg) is used,
it may be possible to forego neutralisation of the condensate
after consultation with the lower water authority.
The condensate may be discharged into drainage pipes only in
accordance with ATV DVGW worksheet A251. Nevertheless,
neutralisation is required if a sufficient quantity of domestic
wastewater (at least 20 times the volume of the expected
amount of condensate) is not added to the condensate.
Connect the siphon supplied to the connectors on the
combustion chamber pan.
Siphon
With a flexible siphon drain hose, form a connection to the on-site
drain (condensate drain level from siphon 260 mm).
When using a condensate pump, route the flexible siphon drain
hose into the condensate pump and form a connection from
there to the on-site drain.
Note: The siphon must be filled with water prior to
commissioning.
If condensate is directly routed to the on-site drain, ventilation
must be provided so that the drain pipe cannot affect the boiler.
Condensate drain with neutralisation
For standard fuel oil EL (sulphur content > 50 ppm),
neutralisation of the condensate is required.
Note: The siphon and the neutralisation box must be filled
with water prior to commissioning.
Siphon
Remove the sealing plug on the siphon plug
NB
before installing the siphon.
If the appliance is operated with an empty siphon,
there is a danger of poisoning caused by escaping
flue gases. For this reason, the siphon must be filled
with water prior to commissioning. Undo, remove
and fill the siphon until water runs out of the side
drain. Refit the siphon and make sure the gasket is
perfectly seated.
Observe the neutralisation box installation
